I'm wondering now how these processors/MCU's handle bus access since you have so many peripherals that probably want to access it as well as the CPU acceses that need to happen. Certainly you have to have a priority settling mechanism and some way of arbitrating the resource. The CPU probably doesn't use it all the time, but if you have a pipeline, it probably uses it in the background anyway.

Start looking up the AMBA (Advanced Microcontroller Bus Architecture) and you'll see how complicated it gets: https://developer.arm.com/architectures/system-architectures/amba https://developer.arm.com/architectures/system-architectures...
